I am a low volume shop. I do all wholesale printing but the majority of my work is wide format printing for signs, vehicle wraps, banners, etc. since we don’t do a ton of screens, I use cap film. Since I can clean a screen and immediately apply film and put it back in the drying cabinet, it saves me a lot of time in cleaning and the mess that is sometimes made with emulsion. It just made sense to spend the $0.75 per screen and get the nice, even coating. The only down side I see is that if you are developing the screen from the inside, sometimes you blow out detail so I wet the inside when I’m done exposing and then develop only from the outside of the screen to make sure that I don’t loose anything.
Some people may say I loose detail because I didn’t apply the film correctly but basic physics says that if something is only on one side of the screen, if you spray from the screen side, you are pushing against the only thing the grabbing onto the screen. If you push from the film side, the grid of the screen provides the strength for the film to hold onto and only blows the non-exposed film through the grid of the screen. Works like a charm.
